Double-Hung Windows

A classic choice that fits naturally in Twin Ports historic neighborhoods, double-hung windows feature two vertically sliding sashes that provide excellent ventilation and a timeless aesthetic. The tilt-in design allows you to clean exterior glass from inside your home, which is a practical advantage that Duluth homeowners appreciate deeply when spring thaw arrives and exterior surfaces need attention.

Casement Windows

When you want to pull a fresh Lake Superior breeze directly into your living space, casement windows deliver. Hinged on the side and cranking outward, they act like a directional sail for airflow. When locked, the sash compresses firmly against the entire frame, creating one of the tightest thermal seals available in residential windows, which matters significantly during a Northland winter.

Sliding Windows

Sliding windows glide horizontally on smooth tracks, making them a clean, practical choice for wide kitchen or basement openings where an outward-swinging unit would create problems. We fit every slider with high-performance weatherstripping that keeps Lake Superior wind on the outside of your home where it belongs, regardless of the season or the storm.

Awning Windows

Hinged at the top and opening outward from the bottom, awning windows create a glass canopy that lets fresh air in even during a light Northland drizzle. This makes them an ideal choice for bathrooms and basements where ventilation and privacy are both required. When closed, the sash seals firmly against the frame, adding a meaningful layer of protection against winter cold and heat loss.

Bay and Bow Windows

Bay and bow windows transform an ordinary wall into a panoramic feature that expands your sense of interior space and frames your property’s best views. These are structural installations handled with full attention to support, insulation, and weatherproofing. The result is a dramatic visual upgrade and a properly sealed, energy-efficient addition your home benefits from year-round.

Picture Windows

When the view outside deserves a clear, unobstructed frame, a picture window is the right answer. These fixed, non-operating units offer the highest possible energy efficiency in their category, functioning as a sealed thermal barrier that floods your interior with natural light while keeping the Northland cold completely outside where it belongs.

Trim and Molding

A new window installed without proper trim work looks unfinished and performs below its potential. We provide expert interior and exterior trim installation using profiles that integrate seamlessly with your home’s existing architecture, from historically appropriate casings in older Duluth neighborhoods to clean modern profiles in contemporary builds and renovations.

Entry Doors

Your front door is the primary thermal and security barrier between your family and a sub-zero January night. We install premium ProVia entry doors with high R-values and your choice of durable steel or fiberglass construction. Every door combines the warmth of a woodgrain aesthetic with the energy performance and security your Twin Ports home demands through every season.

Patio Doors

Connecting your interior living space to an outdoor deck or patio requires a door system built for dramatic temperature swings. Our patio door installations feature multi-pane glass and heavy-duty weatherstripping that keep your home tight and comfortable when lake winds turn aggressive, while opening your space effortlessly to the best of a Northland summer.

Sliding Glass Doors

For layouts where swing clearance is limited and unobstructed sightlines matter, sliding glass doors are a practical and elegant solution. We install Pella and ProVia sliders with advanced thermal breaks and reinforced track systems that maintain smooth, reliable operation through years of freeze and thaw cycling without compromising energy efficiency.

Storm Doors

In the Twin Ports region, a storm door is not optional. It is essential protection for your primary entry against Lake Superior salt air, slush, and sustained wind. Built with tempered glass and sturdy frames, our storm door installations add a meaningful insulation layer to your entrance while allowing natural light and summer ventilation without sacrificing protection.

French Doors

French doors create a wide, elegant passage that transforms any opening into an architectural statement. We ensure a level, precise fit so every set swings smoothly and seals tightly against drafts. Whether you are opening your dining room to the yard for summer entertaining or adding a refined interior transition, the result is high-end aesthetics with the draft protection your home requires.

Caulking and Sealing

The details that protect your home from the elements are often the ones you never see. We apply professional-grade, weather-resistant sealants that stay flexible even when Northland temperatures drop to their worst, creating a fully airtight and watertight perimeter around every installation. This is the step that eliminates the stubborn drafts making your heating bills climb every winter.

Sill Replacement

Window sills in the Twin Ports take a sustained beating from snow accumulation, ice, and relentless freeze and thaw cycling. We replace rotted or compromised sills with rot-resistant materials that provide a solid, level foundation for your windows. Sound sills prevent moisture infiltration, protect your wall framing, and extend the functional life of every window above them.
